Deck Counterweight Spring Installation
5. Raise mower body (instead of lifting the front of
deck) and clip the counterweight springs to the
receptacle on front of body. Lower the body to
tension the springs. (Refer to Deck Counter-
weight Spring Installation photo.)
6. With the counterweight springs connected, the
weight on the deck caster wheels should be 15
to 25 Ib (6.8 to 11.3 kg). Check this weight by lift-
ing on the front of the deck carrier frame. If
required, the spring tension can be adjusted by
tightening or loosening the elastic stop nuts lo-
cated underneath the lower spring hook. Refer
to Deck Counterweight Spring Installation
photo.
